President Volodymyr Zelenskyy says he will urge allies to boost Ukraine’s air defenses at a meeting this week in Germany, while both sides said Kyiv’s forces pressed new attacks Sunday in Russia’s Kursk region.

Russian forces continue to make costly but consistent gains in the Donetsk region in eastern Ukraine. They are steadily grinding down a pocket of resistance around the town of Kurakhove and are also fighting to envelop the larger nearby city of Pokrovsk, Ukrainian soldiers and officials said.

Ukraine has launched a fresh offensive in Russia's Kursk region, the Russian defence ministry says. In a statement, the ministry said efforts to destroy the Ukrainian attack groups were ongoing. Officials in Ukraine have also suggested an operation is under way.
